Question

The degree of the function f(x) = -(x + 1)2(2x − 3)(x + 2)2 is??????and its y-intercept is?????

Answer 1

Find degree by finding the highest power of 'x'. Long way is to multiply out all the terms. Short way is to find all the highest power s in the product, and add the exponents. so (x+a)^4 * (x^2+1)^3 has degree 10 (4*1 + 3*2)

To find y-intercept, find f(x=0)
